FBCA signed ORC ACES 4 Intermediate CA Certificate – This CA signing certificate is signed by the Federal Bridge Certificate Authority. The purpose of this certificate is to allow applications to chain the ACES certificate authority up to the Federal Common Policy Root certificate. The Federal Common Policy and Federal Bridge CA exist to promote PKI interoperability between different Federal Government agencies. However, the cross-signed certificate trust chain can be more difficult to use. An application will only use one trust chain or the other so this should be considered an ‘either-or-proposition’; either use the trust chain made up of the ORC Root 2 and ORC ACES 4 Intermediate CA certificates above – OR – use the certificate indicated in this link.
